This sensor measures machine vibration velocity (mm/s RMS) and converts it directly into a standard 4-20mA analog current loop output for PLCs, SCADA systems, or data loggers.
This specific unit was manufactured in 2016 (Serial Number: 606716). It is in excellent physical condition and has been fully bench-tested. It outputs a rock-solid 4.0 mA at rest and responds accurately to motion. Because piezoelectric sensors contain no moving parts, they have an incredibly long service life and remain highly reliable over time.
Key Technical Specifications:
Model: Monitran MTN/1185M-1000
Output: 2-wire loop-powered (4-20mA)
Supply Voltage: 12–32 V DC
Connection: 3-pin industrial connector (MIL-spec / Amphenol 62GB)
Mounting: Metric male thread (M-variant)
Special Features: Factory M-1000 variant with a built-in 1000 Hz high-pass filter. Perfectly optimized for monitoring high-frequency faults like fast-rotating bearings and gear mesh while filtering out low-frequency background machinery rumble.
Construction: Stainless steel, Base Isolated (prevents ground loops).

Please Note: This listing is for the sensor only; no cable is included. It uses a standard Monitran MTN/CA137 cable assembly, or you can build your own using a standard Amphenol 62GB-16F08-03SN / PT06A-8-3S connector.
